REVOLVING WATER-CLOSET STENCH- TRAP.

i O SPECIFICATION forming part of Letters Patent No. 274,725, datedMarch 27, 1883.

Application filed Febi-uary 6, 1883. (No model.)

Toctll whom it may concern:

Be it known that I, LEE D. URAIG, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented a new and useful Improvement in Revolving Water-Closetstench-Traps, of which the following is a specification.

My invention relates to revolving water-closet stench-traps. The objectof the invention is to exclude more efl'ectually the noxious gases whicharise from sewers and penetrate water-closets and other parts ofdwelling-houses and other occupied buildings. My aim, further, is toaccomplish this exclusion of the gases by simple means, which shall notbe expensive to make, and shall not be liable to get out of order inuse.

In the accompanying drawings, Figure 1 represents a central verticalsection of the trap, taken through the axis of the revolving box. Fig. 2is a like section taken at right angles to the first. Fig. 3 is ahorizontal section on line of the axis.

In these figures, A represents an ordinary bowl of a water-closet. Itsopen bottom is united with air-tight joint to an openingin the upperside of a cylindrical case, 1, set with its ends invertical planes.Underneath'and directly opposite the opening to the bowl is an otheropening into the discharge-pipe J, to which the case is also joined byair-tight con nections. Within this case is suspended a double box,B, ona shaft, E, to which it is fixed. This shaft has hearings in thevertical ends of the cylinders through which it passes. The box isfitted to the cylinder so as to revolve It is divided into two equalparts by a central transverse partition, 0, dividing it into two equalparts or boxes having a common bottom and open ends. In

gases between the box ends and the junction of the ends with the seatabove and the discharge-pipe below, I have set packings H H p i preferto attach to the she ftby means of a pawl and ratchet, and connect thewheel to a bandle, G, on the outside of the seat by means of a strap, sothat when the handle is raised it pulls upon the strap and'turns thewheel F, which, by means of its pawl engaging with the ratchet on theshaft, turns the shaft and inverts the box. As the wheel F is loose uponthe shaft, it mustbe returned while the handle Gr has dropped. This Iaccomplish by means of a spring or weight. The lift of the handle shouldbe limited, so as to exactly invert the box and no more. The inversionof the box carries its contents, received from the bowl, around anddischarges them'into the dischargep ne In order to flush the box, Iprovide an opening, i, near the center of the box, upon one side of thewall. This opening enters the box at an inclination directed toward thebottom or partition G, and underneath a perforated false bottom, D,there being one of these for each every operation of the handle G. Atube leads also from the reservoir T into the bowl A.

What I claim as my inventiomand desire to secure by Letters Patent, is

. 1. The combination of thebowlA, dischargepipe J, and the revolving boxB, having compartments, as described, and registering with the openingin the bowl and the dischargepipe, with the case I, and means, asdescribed, for revolving the box.
